Book Description
Enzyme Catalysis and Regulation is an introduction to enzyme catalysis and regulation and covers topics ranging from protein structure and dynamics to steady-state enzyme kinetics, multienzyme complexes, and membrane-bound enzymes. Case studies of selected enzyme mechanisms are also presented. This book consists of 11 chapters and begins with a brief overview of enzyme structure, followed by a discussion on methods of probing enzyme structure such as X-ray crystallography and optical spectroscopy. Kinetic methods are then described, with emphasis on the general principles of steady-state and transient kinetics. The chemical principles involved in enzyme catalysis are also discussed, and case studies of a few well-documented enzymes are presented. The regulation of enzyme activity is analyzed from a nongenetic viewpoint, with particular reference to binding isotherms and models for allosterism. Two particular enzymes, aspartate transcarbamoylase and phosphofructokinase, are used as examples of well-studied regulatory enzymes. The last two chapters focus on multienzyme complexes and membrane-bound enzymes. This monograph is intended for graduate students, advanced undergraduates, and research workers in molecular biology and biochemistry.

Book Description
This enzymology textbook for graduate and advanced undergraduate students covers the syllabi of most universities where this subject is regularly taught. It focuses on the synchrony between the two broad mechanistic facets of enzymology: the chemical and the kinetic, and also highlights the synergy between enzyme structure and mechanism. Designed for self-study, it explains how to plan enzyme experiments and subsequently analyze the data collected. The book is divided into five major sections: 1] Introduction to enzymes, 2] Practical aspects, 3] Kinetic Mechanisms, 4] Chemical Mechanisms, and 5] Enzymology Frontiers. Individual concepts are treated as stand-alone chapters; readers can explore any single concept with minimal cross-referencing to the rest of the book. Further, complex approaches requiring specialized techniques and involved experimentation (beyond the reach of an average laboratory) are covered in theory with suitable references to guide readers. The book provides students, researchers and academics in the broad area of biology with a sound theoretical and practical knowledge of enzymes. It also caters to those who do not have a practicing enzymologist to teach them the subject.

Book Description
Current Topics in Cellular Regulation: Volume 24, Enzyme Catalysis and Control is a compendium of papers that discusses phosphoryl transfer reactions, the role of water on the free energy of hydrolysis of pyrophosphate, and the hormonal actions of vitamin D. Other papers describe the regulation lipid metabolism by a lipid-carrying protein, the GABA, and taurine enzymes in mammalian brain. One paper examines the role of vitamin D in the metabolism of cells, as well as in the whole animal. Upon absorption in the body, the vitamin undergoes various metabolic transformations before interacting with specific receptors, and then inducting the genome in the target tissues to generate biological and hormonal responses. Another paper notes the possibility of a genetic defect in cancer cells that results in the abnormal accumulation of sterol carrier protein (SCP) and cholesterol in vivo; and also in the inability to maintain levels of SCP or cholesterol in vitro. One paper shows that tartrate, or other organic acids, secreted into the medium by the penicillia keeps the pH in an optimal range for acid protease degradation of proteins and glycoproteins. This mechanism helps the fungus to survive in a nutrient environment (which is unbalanced with respect to an optimum C/N ratio and at a pH unfavorable to many bacteria and other life forms). Another paper proposes a model for the modulation of ATP synthetase activities and medium exchange reactions by energy input, substrate concentration, or others that affect the microenvironment of the enzyme under certain conditions. The compendium will prove beneficial to molecular biologists, general biologists, microbiologists, and biochemists.

Book Description
Far more than a comprehensive treatise on initial-rate and fast-reaction kinetics, this one-of-a-kind desk reference places enzyme science in the fuller context of the organic, inorganic, and physical chemical processes occurring within enzyme active sites. Drawing on 2600 references, Enzyme Kinetics: Catalysis & Control develops all the kinetic tools needed to define enzyme catalysis, spanning the entire spectrum (from the basics of chemical kinetics and practical advice on rate measurement, to the very latest work on single-molecule kinetics and mechanoenzyme force generation), while also focusing on the persuasive power of kinetic isotope effects, the design of high-potency drugs, and the behavior of regulatory enzymes. Historical analysis of kinetic principles including advanced enzyme science Provides both theoretical and practical measurements tools Coverage of single molecular kinetics Examination of force generation mechanisms Discussion of organic and inorganic enzyme reactions
